摘要： The invention relates to platelet-shaped pearlescent pigments which are coated with at least one mixed inorganic/organic layer for improving their application properties, and in this case, particularly, their mechanical properties, and to a method for the production and use thereof. Said mixed inorganic/organic layer comprises at least one partially cross-linked inorganic metal oxide component and an organic component, which is at least one organic oligomer and/or polymer which is covalently bonded, at least in part, to the inorganic network via crosslinkers. The coating is provided with at least one mixed inorganic/organic layer which contains, at least in part, an inorganic network encompassing one or several inorganic oxide components, and at least one organic component which at least partly represents an organic oligomer and/or polymer that is covalently bonded at least in part to the inorganic network via one or several organic network formers. The invention also relates to a method for producing said type of pearlescent pigments.

摘要： The invention relates to weather-resistant pearlescent pigments which have improved application properties and are based on a small glass plate that is coated with highly refractive metal oxides and a protective coating located on the top metal oxide layer. The inventive pigments are characterized in that the small glass plate has an average thickness of 50 to 500 nm. According to variant A, a metal oxide layer whose refractive index n exceeds 1.8 and which comprises TiO2 having a rutile concentration ranging from 80 to 100 percent by weight as well as a protective SiO2 coating are applied. According to variant B, a metal oxide layer whose refractive index n exceeds 1.8 and which comprises TiO2 having a rutile concentration ranging from 80 to 100 percent by weight as well as a protective coating containing a first protective layer with cerium oxide and/or cerium oxide hydrate and/or cerium hydroxide and a second protective SiO2 layer are applied. Additionally, an organic chemical surface coating is applied to the metal oxide layer of the protective coating of A or B. The invention further relates to a method for producing said pigments and the use thereof.
